Реферат: The invention relates to a control mechanism (1) for a gas boiler (2) for combusting combustion gas, the mechanism (1) comprising a flame sensor (3) for detecting the presence of a flame, an ionization electrode (4) for detecting an ionization current, and a control unit (5) to control the operation of the boiler (2), said control unit (5) being connected to the flame sensor (3) and the ionization electrode (4) to acquire a flame detection signal and an ionization detection signal, respectively, wherein the control unit (5) is configured to selectively set a first operating mode, a second operating mode and a third operating mode dependent on the acquired flame detection signal and/or the acquired ionization detection signal, wherein the first operating mode is set when the combustion gas comprises hydrogen with a concentration that corresponds to or is greater than a first predetermined value and the second operating mode is set when the combustion gas comprises hydrocarbon and hydrogen, wherein the concentration of hydrogen is greater than a second predetermined value and lower than the first predetermined value and the third operating mode is set when the combustion gas comprises hydrocarbon and hydrogen, wherein the concentration of hydrogen corresponds to or is lower than the second predetermined value.
